Network amplifier with microprocessor control

The present invention relates generally to the field of telecommunications and, in particular, to a network amplifier for a cable network. A network amplifier is provided. The network amplifier includes a variable equalizer having at least one control input and a variable attenuator having at least one control input. The network amplifier also includes at least one amplifier circuit that is coupled in series with the variable equalizer and the variable attenuator in a signal path of the network amplifier. The network amplifier also includes an automatic gain control circuit with a processor that monitors signals in the signal path and generates control signals for the control input of the variable equalizer and the control input of the variable attenuator to control at least one characteristic of the network amplifier.
